Abstract

Line systems passing through the origin of the d-dimensional Euclidean space admitting exactly two distinct angles are called biangular. It is shown that the maximum cardinality of biangular lines is at least 2(d - 1)(d - 2), and this result is sharp for d is an element of{4, 5, 6}. Connections to binary codes, few-distance sets, and association schemes are explored, along with their multiangular generalization.
